Triangular and Y-shaped hadrons with static sources

The structure of hadrons consisting of three static color sources in fundamental (baryons) or adjoint (three-gluon glueballs) representations is studied. The static potentials of glueballs as well as gluon field distributions in glueballs and baryons are calculated in the framework of field correlator method.Comment: 7 pages, 5 figures, talk at the NPD-2002 Conference, December 2-6, ITEP, Moscow, reference adde

Mega-clusters as a tool of interregional cooperation in tourists field

In order to diversify the Russian economy, it is necessary to pay great attention to the emerging sectors of the economy; with a systemic approach they are able to reveal their accumulated potential. Authors consider one of such industries to be the sphere of tourism. Russia has its own unique natural-recreational and cultural-historical potential, which is not fully utilized, and it is confirmed with the relevant statistics. The authors propose to accelerate the development of tourism by raising the level of interregional cooperation from the position of using coexisting competition and competitive coexistence in tourist mega-clusters. Due to the lack of financial resources for separate regions for the tourism development, the implementation of this approach is effective, as it allows achieving savings of money due to economies of scale. The phenomena of coexisting competition and competitive coexistence in the tourism sphere presuppose the unification of the different regions authorities’ efforts for the joint implementation of projects. Regions joining forces on the basis of coexisting competition and competitive coexistence within the mega-clusters will allow each administrative-territorial unit to develop and improve its competitive advantage by asking a stimulus to the development of the other participants. This approach makes it possible to obtain other positive effects noted in the study. Thus, findings broaden the knowledge about the phenomena of coexisting competition and competitive coexistence in the regional economy, about mega-clusters as tools for interregional interactions in the tourism sphere

CORRELATION-EXTREME NAVIGATION SYSTEM BASED ON MORPHOLOGICAL ANALYSIS

Therefore, advantage of morphological method is associated with the possibility of improving the integration of image registration conditions. Introduced by morphological analysis the notion of «form» significantly enriches the radiometric properties of reference image, making possible to build a more robust detection algorithms

Phonon switching and combined Fano-Rice effect in optical spectra of bilayer graphene

Recent infrared measurements of phonon peaks in gated bilayer graphene reveal two striking signatures of electron-phonon interaction: an asymmetric Fano lineshape and a giant variation of the peak intensity as a function of the applied gate voltage. In this Letter we provide a unified theoretical framework which accounts for both these effects and unveils the occurrence of a switching mechanism between the symmetric ($E_g$) and anti-symmetric ($E_u$) phonon mode as dominant channel in the optical response. A complete phase diagram of the optical phonon response is also presented, as a function of both the charge density and the bandgap.Comment: final versio

Charged-phonon theory and Fano effect in the optical spectroscopy of bilayer graphene

Since their discovery, graphene-based systems represent an exceptional playground to explore the emergence of peculiar quantum effects. The present paper focuses on the anomalous appearence of strong infrared phonon resonances in the optical spectroscopy of bilayer graphene and on their pronounced Fano-like asymmetry, both tunable in gated devices. By developing a full microscopic many-body approach for the optical phonon response we explain how both effects can be quantitatively accounted for by the quantum interference of electronic and phononic excitations. We show that the phonon modes borrow a large dipole intensity from the electronic background, the so-called charged-phonon effect, and at the same time interfer with it, leading to a typical Fano response. Our approach allows one to disentangle the correct selection rules that control the relative importance of the two (symmetric and antisymmetric) relevant phonon modes for different values of the doping and/or of the gap in bilayer graphene. Finally, we discuss the extension of the same theoretical scheme to the Raman spectroscopy, to explain the lack of the same features on the Raman phononic spectra. Besides its remarkable success in explaining the existing experimental data in graphene-based systems, the present theoretical approach offers a general scheme for the microscopic understanding of Fano-like features in a wide variety of other systems.Comment: 16 pages, 11 eps figures, PR

Специфіка інфантичної мовної картини світу

У статті розглядаються особливості структури лексичної репрезентації інфантичної мовної картини світу. Проаналізовано дослідження вчених у галузі «картина світу», «псіхолігія дитини», «дитяча мова». На підставі дослідження англомовних віршованих інфантіческіх текстів встановлено специфічні базиси лексичного наповнення мовлення інфанта при вербалізації картини світу. (Recently, the interest of linguists to the language and its relations with the environment, in particular to ethnic, gender, ecological and other aspects of language has increased use significantly. Is no exception to this system and biovital aspect of speech activity, which prominently includes infant language. It’s not just the language of children, but also intelligent products that are made by adults for children use -literature for children. A lot of papers are devoted to the description of children’s literature in terms of its verbal arrangements, while scientific researches on poetic works for children are rare. The current relevance of the article is in the complex investigation of lingual English poetic infant texts in the light of the analysis of the linguistic world picture. To solve this problem, first of all it is needed the multifaceted study of speech in infant texts – books for preschool children and children’s literature, which is precisely the subject of the research. The purpose is to find out the features of lexis of infant linguistic world view, and the object is verbal means of expression of infant world view... Infant lingual world view is a special way of conceptualizing reality, displaying specific physical and mental realities in the language of children. In substantive terms of the language of children and their implementations the speech is represented with a special level of the world views, a special look at the world. Any changes that are presented in the language of the child is the result of a particular integral conception of the world, which is formed in the collective minds of children.

The QCD vacuum, confinement and strings in the Vacuum Correlator Method

In this review paper the QCD vacuum properties and the structure of color fields in hadrons are studied using the complete set of gauge-invariant correlators of gluon fields. Confinement in QCD is produced by the correlators of some certain Lorentz structure, which violate abelian Bianchi identities and therefore are absent in the case of QED. These correlators are used to define an effective colorless field, which satisfies Maxwell equation with nonzero effective magnetic current. With the help of the effective field and correlators it is shown that quarks are confined due to effective magnetic currents, squeezing gluonic fields into a string, in agreement with the ``dual Meissner effect''. Distribution of effective gluonic fields are plotted in mesons, baryons and glueballs with static sources.Comment: 36 pages, 19 figures, to appear in UFN, updated version.
